[Daniel van Vugt (vanvugt)]

This appears to be bug 1867668. You can either uninstall the old buggy driver:

  sudo apt remove xserver-xorg-video-intel

or just avoid it by selecting 'Ubuntu on Wayland' at the login screen.

[Jarvis Yadav (jarvisydv0069)]

The glitch appears on splash screen itself so switching to wayland did nothing.. uninstalling the old driver xserver-xorg-video-intel and rebooting switched the driver to modesetting but still the issue is there everytime.. the video of the error can be seen here
https://www.youtube.com/watch?v=GcAXAicoZqY

[Daniel van Vugt (vanvugt)]

If the problem occurs in Wayland and also after uninstalling the old driver, then it sounds like either a kernel bug or a hardware connection problem.

It looks like this is a desktop but with a laptop screen. Is that right?

[Daniel van Vugt (vanvugt)]

Please:

1. Reboot.

2. Log into a Wayland session and ensure the bug is happening.

3. While the bug is happening run:

   journalctl -b0 > journal.txt

4. Attach the resulting text file here.

[Jarvis Yadav (jarvisydv0069)]

Attached the journal.txt

Thanks for your reply...
Yes my device is an HP omni 120 all in one series desktop..

[Daniel van Vugt (vanvugt)]

In the past when people had trouble with HP all-in-one screens, the solution was:

 1. Beware! Backup you data! You will likely need to reinstall Ubuntu after this.
 2. Go into the BIOS and toggle the legacy mode/secure boot settings.
 3. Reinstall Ubuntu.

[Jarvis Yadav (jarvisydv0069)]

Ok I will try this just now and check the results.. Thanks for your time..

[Jarvis Yadav (jarvisydv0069)]

So here's an update,
It seems like I don't have the 'Secure Boot' Option in my bios so I couldn't test it.
I disabled UEFI devices from my bios and that forced it to use legacy boot devices only (Sandisk Cruzer Blade in the above video is my bootable pendrive from which I am installing ubuntu)
Then reinstalled Ubuntu, but still the issues are same..
Here is a video of bug during the installation process- https://www.youtube.com/watch?v=1VMa3WcwaYQ
And here is a video of the startup process- https://www.youtube.com/watch?v=lIZj-oHXCHs

My BIOS doesn't have a direct option to switch to legacy or UEFI mode, so I disabled UEFI devices to force it to use legacy mode (and that's why there are not UEFI boot sources in the video above)
In short- Nothing Changed, Everything is the same
Also since Windows 10 works fine on the device I don't think that there is any damage or fault in the hardware

[Daniel van Vugt (vanvugt)]

Please try adding kernel parameter:

  i915.enable_psr=0

which you can do in /etc/default/grub as part of the GRUB_CMDLINE_LINUX_DEFAULT line. Then run:

  sudo update-grub

and reboot.

[Jarvis Yadav (jarvisydv0069)]

Here is a screenshot of the grub file
Added parameter, updated the grub and rebooted but nothing has changed... The flickering lines are still there

[Daniel van Vugt (vanvugt)]

To be sure it applied properly, what is the contents of /proc/cmdline ?

[Jarvis Yadav (jarvisydv0069)]

BOOT_IMAGE=/boot/vmlinuz-5.11.0-27-generic root=UUID=6ee9af7d-b744-419e-91ba-9ccff120f42b ro quiet splash i915.enable_psr=0 vt.handoff=7

content of /proc/cmdline

[Daniel van Vugt (vanvugt)]

My only remaining suggestions are:

 * Try a newer kernel, or more simply try Ubuntu 22.04 which contains a newer kernel: http://cdimage.ubuntu.com/daily-live/current/ ; or

 * Use the nomodeset kernel parameter :(

[Jarvis Yadav (jarvisydv0069)]

If i use the nomodeset parameter what things would get disabled?
Will I get slow performance with nomodeset parameter?

[Jarvis Yadav (jarvisydv0069)]

I would like to ask one more thing, Should I try some other liunx distribution such as fedora or linux mint or something else that you can suggest? Will changing the distro fix this issue? :(

[Jarvis Yadav (jarvisydv0069)]

Btw I am trying to install kernel 5.15.32.. Will let you know if things change..

[Daniel van Vugt (vanvugt)]

I don't think changing distro will fix it.

The final thing to try is the latest 'drmtip' kernel:

  https://kernel.ubuntu.com/~kernel-ppa/mainline/drm-tip/

If the bug still isn't fixed in that latest kernel then you should report it to the kernel graphics developers at:

  https://gitlab.freedesktop.org/drm/intel/-/issues

Additional info:

  https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs

[Jarvis Yadav (jarvisydv0069)]

Ok I will try 'drmtip' kernel, and report it as well in case it's not fixed.. But I would like to ask what if I use the "nomodeset" parameter.. What compromises would be there in using nomodeset?

[Daniel van Vugt (vanvugt)]

nomodeset really is a temporary workaround. It disables the GPU hardware acceleration, and in some cases might prevent you from even getting the correct screen resolution.

[Jarvis Yadav (jarvisydv0069)]

Can you help me out in installing the latest drmtip kernel.. Whenever I try to install drmtip kernel it shows error like,
"linux-headers-***-generic depends on libc6(>= 2.34) however Version of libc6 on system is 2.31
Package libssl3 is not installed"
I think I will have to compile the latest drmtip kernel to overcome these dependency issues.. I don't know how to compile the drmtip kernel.. Help would be appreciated.

[Daniel van Vugt (vanvugt)]

That's a little too complex to explain here.

Instead please try booting Ubuntu 22.04 from USB to see if it has the same bug:
http://cdimage.ubuntu.com/daily-live/current/

If you are willing to also install 22.04, and the bug still isn't fixed there, then the drm-tip kernel should install more easily on that.

[Camilo QS (vxcamiloxv)]

I have the same issue, I just tested last daily ubuntu iso lunar-desktop-amd64.iso (2023-02-16 08:22) and same issue

HP Omni 120
Intel Core i5-2400S
Intel graphics 2000 - Mesa Intel® HD Graphics 2000 (SNB GT1)

[Daniel van Vugt (vanvugt)]

Camilo, can you attach a video of your issue?

[Richard Marwitz (rhmarw)]

I also have the same issue. It is the same as described in the the original post. My screen looks exactly like the video attached above. I am running Ubuntu 22.04.1 on an HP All in One 120-1031.

If I use NOMODSET the lines do not appear but the screen is too large to use.

Also if I use VNC to view the desktop remotely Everything looks good.

[Daniel van Vugt (vanvugt)]

Please try the workaround in comment #13.

[Richard Marwitz (rhmarw)]

I tried the workaround in comment #13. The screen still has the lines.

[Saija Tuiskula (saikkuli)]

I installed Ubuntu 22.04.2 LTS (Jammy Jellyfish) with Legacy safe graphics mode.

 After installation open terminal
and do the following (able to do despite the flikering):

Sudo nano /etc/defaul/grub

add nomodeset to GRUB_CMDLINE_LINUX_DEFAULT:

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
GRUB_CMDLINE_LINUX=""

Then save by hitting Ctrl+O enter, exit nano whit Ctrl+X

Then run:

sudo update-grub

sudo reboot. (Rebooting doesn't work. Needs to shut down and restart?)

Now lines do not appear but the screen is large

Next still whit terminal.
xrandr_____ to see which Display is in use. (My was default)

$cvt 1600 900 (At this point there were several bug reports, I didn't care)

$cvt 1600 900
# 1600x900 59.95 Hz (CVT 1.44M9) hsync: 55.99 kHz; pclk: 118.25 MHz
Modeline "1600x900_60.00" 118.25 1600 1696 1856 2112 900 903 908 934 -hsync +vsync

$xrandr --newmode "1600x900_60.00" 118.25 1600 1696 1856 2112 900 903 908 934 -hsync +vsync

$xrandr --addmode default "1600x900_60.00"

$ xgamma
-> Red 1.000, Green 1.000, Blue 1.000 (For some strange reason this had to be done, otherwise it didn't work)

then

$sudo nano /etc/default/grub

find the line exsample:

#GRUB_GFXMODE=1024x768 (maybe something else)

edit 1024x786 to your resolution: 1600x900, remove the #

example:

GRUB_GFXMODE=1600x900

update by the command

$sudo update-grub

Then reboot your computer

$sudo reboot

This is what I done whit my HP Omni 120-1100eo Desktop PC

Attached video of HP Omni 120 Flickering, I tested with kernel 6.0, 6.1, 6.2 (compiled by my self using drm-tip branch), and 6.2 from 23.04, now testing 6.3, same issue, the only workaround is "nomodeset i915.modeset=0"

[Camilo QS (vxcamiloxv)]

I reported the issue to intel/freedesktop and was fixed https://gitlab.freedesktop.org/drm/intel/-/issues/8895#note_2005508, I guess it will be included in the next kernel version.

[Leon Le (iamleon)]

@Camilo QS, Could you please show me how to fix? I'm suffering from the same problem?

[Leon Le (iamleon)]

Solution: Build a kernel for HP Omni 120 based on Linux kernel 6.4.13

Step 1: Download Linux kernel 6.4.13 and extract:
"wget https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.4.13.tar.xz"
"tar xvf linux-6.4.13.tar.xz"

Step 2: Install additional packages for building a kernel
"sudo apt-get install git fakeroot build-essential ncurses-dev xz-utils libssl-dev bc flex libelf-dev bison"

Step 3: Configure Kernel
Navigate to the linux-6.4.13 : "cd inux-6.4.13"
Copy the existing Linux config file: "cp -v /boot/config-$(uname -r) .config"
Make a default configuration file: "make menuconfig" -> Save -> Exit

Step 4: Edit drivers/gpu/drm/drm_edid.c in folder linux-6.4.13 (Visit https://gitlab.freedesktop.org/nouvelles/kernel/-/commit/2682768bde745b10ae126a322cdcaf532cf88851 for more details)
Remove
 /* Some EDIDs have bogus h/vtotal values */
 if (mode->hsync_end > mode->htotal)
  mode->htotal = mode->hsync_end + 1;
 if (mode->vsync_end > mode->vtotal)
  mode->vtotal = mode->vsync_end + 1;
Add
 /* Some EDIDs have bogus h/vsync_end values */
 if (mode->hsync_end > mode->htotal) {
  drm_dbg_kms(dev, "[CONNECTOR:%d:%s] reducing hsync_end %d->%d\n",
       connector->base.id, connector->name,
       mode->hsync_end, mode->htotal);
  mode->hsync_end = mode->htotal;
 }
 if (mode->vsync_end > mode->vtotal) {
  drm_dbg_kms(dev, "[CONNECTOR:%d:%s] reducing vsync_end %d->%d\n",
       connector->base.id, connector->name,
       mode->vsync_end, mode->vtotal);
  mode->vsync_end = mode->vtotal;
 }

Step 5: Start building the kernel. Note: It may take hours to complete.
"scripts/config --disable SYSTEM_TRUSTED_KEYS"
"scripts/config --disable SYSTEM_REVOCATION_KEYS"
"sudo make -j$(nproc)"
Press Enter 2 times to confirm the default options for the generation of new certificates.

Step 6: Install the compiled kernel
"sudo make modules_install"
then
"sudo make install"

Reboot and the flickering disappear. This issue has been existing for over a decade, so I hope anyone suffering from this issue can now fix it.

[Camilo QS (vxcamiloxv)]

FYI this is available in kernel version 6.7-rc7 and will be included in final release of linux kernel 6.7
